“…Interestingly, the fluorescence intensity of L‐Cu 2+ solution decreased to a lower value after addition of Pb 2+ ; this cold be attributed to closure of the fluorescence group of probe H 2 L , resulting in a decrease in L‐Cu 2+ fluorescence. [ 64 ] Other metal ions had little effect on the recognition of Cu 2+ using probe H 2 L , and reflected the probe specificity.…”

An asymmetric salamo‐based probe molecule (H2L) was synthesized and characterized structurally. When DMF/H2O (9:1) was used as the solvent, it was shown probe H2L has high sensitivity to Cu2+. Using high‐resolution mass spectrometry and theoretical calculation, it was found that probe H2L could form a more stable complex (1:1) with Cu2+, the minimum limit of detection (LOD) of H2L for Cu2+ was calculated as 9.95 × 10−8 M. In addition, probe H2L could also be used to identify B4O72− under the same detection conditions and the minimum LOD of H2L for B4O72− was calculated as 4.98 × 10−7 M. At the same time, density functional theory theoretical calculation further proved the flexibility of probe H2L. Through the action of EDTA, probe H2L had a cyclic ability to recognize Cu2+, and showed a better response in the physiological pH range; probe H2L had the characteristics of fast recognition speed and high efficiency. In addition, with probe H2L test paper for Cu2+ and B4O72−, the effect was more obvious. Meanwhile, probe H2L can be used to quantitatively detect Cu2+ in water samples.

“…The proposed sensor can easily be prepared, eco‐friendly in nature, cost effective, quick response time and high sensitivity signifying the greater advantages over other existing Zn 2+ ions' sensors. [ 16–19 ] Though there are several techniques applied for the detection of Zn 2+ ions but to the best of our knowledge electrochemical sensing of Zn 2+ by PAg NPs is very rare. Therefore, the detection of trace Zn 2+ ions by electrochemical technique using PAg NPs has considerable research interest.…”

Herein, we report a highly sensitive, selective and simple electrochemical sensor for the detection of Zn2+ ions in less than 1 nM concentration range in aqueous environment. A naturally occurring and frequently cultivated Tricholoma mushroom polysaccharide is used for the preparation of novel sensor. In the present investigation we demonstrate an electrochemical sensor, grafted Tricholoma mushroom polysaccharide‐based silver composite nanoparticles (TMPSGP‐Ag NPs) which show remarkable electrochemical sensing performance of Zn2+ ions without interfering with the other relevant metal ions. The sensing performance is carried out by cyclic voltammetry (CV) and chronoamperometry (CA) analysis under optimised condition. The limit of detection (LOD) is found to be 0.53 nM, which is much lower than some other reported works as well as lower than the limit of World Health Organization (WHO). The stability, reproducibility and repeatability properties of the sensor are examined where a satisfactory result is obtained. The practical application of the proposed sensor is tested by the detection of Zn2+ ions using river water sample with an excellent performance. Therefore, the developed sensor can be used as a highly efficient and effective Zn2+ ions detector in aqueous medium.

“…Salen and its derivatives (CHN[CH] n NCH) are used in various fields due to their excellent properties and interesting structures. Some complexes can be applied to molecular recognitions, [ 1–5 ] catalysts, [ 6–8 ] supramolecular architectures, [ 9–14 ] magnetic materials, [ 15 ] and fluorescence materials. [ 16–19 ] Salen‐based compounds have been improved, two salicylaldehyde molecules ligated with an alkoxyl bridging unit as a linker form a new structural configuration (CHNO[CH] n ONCH) of salamo‐based ligand.…”

Two newly designed heteromultinuclear [CuII4SmIII2] and [CuII2TbIII] bis (salamo)‐based complexes, [{Cu2(L)Sm (NO3)2(μ2‐NO3)(CH3OH)}2]·2CH3OH and [Cu2(L)Tb (NO3)2(μ2‐NO3)][Cu2(L)Tb (NO3)2(μ2‐NO3)(H2O)]·CH3OH, were synthesized and characterized by elemental analyses, Fourier transform infrared (FT‐IR) spectra, ultraviolet–visible (UV–vis) absorption spectra, and X‐ray crystallography. The ultraviolet titration experiments exhibited that the coordination ratio of the ligand, rare earth metal, and transition metal is 1:1:2. In the [CuII4SmIII2] complex, Cu1 atom has a distorted quadrilateral pyramid geometry, whereas Cu2 atom forms a slightly distorted octahedral geometry. The [CuII2TbIII] complex unit cell contains two crystallographically independent and chemically different heterotrinuclear complexes (Molecules A and B). In Molecule A, the Cu1 atom bears a four‐coordinated plane quadrilateral geometry, whereas the five‐coordinated Cu2 atom forms a slightly distorted tetragonal cone geometry. In Molecule B, the five‐coordinated Cu3 and Cu4 atoms possess slightly distorted tetragonal cone geometries. Noncovalent interactions like hydrogen bonding and π···π stacking interactions are operative in construction of supramolecular architectures. The [CuII2TbIII] complex behaves as a catalyst towards oxidative coupling of 2‐AP in MeCN medium. In addition, fluorescence properties of the ligand H4L and its [CuII4SmIII2] and [CuII2TbIII] complexes have also been discussed.
